Answer: The GCF is 4
Explanation: The factors of 52 are 52, 26, 13, 4, 2, 1. The factors of 92 are 92, 46, 23, 4, 2, 1. So the GCF is 4.
Answer:
The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.
Explanation:
Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.
With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.

D. Beowulf asks King Hrothgar to allow him and his men to destroy Grendel.
Answer:
The correct answer is B) Large size relative to the host chromosomes
Explanation:
A vector for clonation or expression must contain sequence elements which allow it independent replication and identification of host cells which have incorporated the vector. Among these elements are:
- Replication origin (option E): allows it to replicate independently of the host genome. Option B is the same as it.
- Restriction enzyme sites (option A): in order to cut the vector and to inser the desired gene into the vector.
- Reporter gene (option E): it allows to visualize the host cells which are expresing the inserted gene of the vector. For example, a reporter gene can codificate a fluorescent protein, thus the host cells which have expresion of the vector are fluorescent.
The only option which is unuseful is option B because if the vector has too large size, the transformation efficiency will be low. That means that fewer host cells will contain the vector after transformation.
There are two ways you could look at this. If we got rid of all viruses, then less people would die. This is obviously a good thing as so many families are devastated by virus related deaths every year. However, all these extra people could lead to surplus population which, as history has shown, leads to drought, famine, and the eventual down fall of the empire/nation/etc
